Abstract: The present disclosure is directed to a reciprocating saw assembly including a saw unit. The saw unit includes a reciprocating mechanism having a reciprocating spindle to which a saw blade is attachable, a drive unit for providing torque to the reciprocating mechanism, causing the spindle to reciprocate, and an outer housing in which the drive is received. The outer housing includes a handle portion graspable by a user during a cutting operation. The reciprocating saw assembly further includes a clamping unit having a clamp housing pivotably coupled to the outer housing and a jaw movable relative to the clamp housing between a clamping position, in which the clamping unit is affixed to a workpiece to be cut, and a release position, in which the clamping unit is removable from the workpiece.

Abstract: A saw system capable of cutting through a workpiece in one stroke is provided. The saw system includes a base, a turntable mounted on the base for rotation about a vertical axis, a support structure defining a cutting axis and fixedly attached to the turntable, and an elongated blade including a cutting edge. The turntable has a substantially planar support surface for supporting a workpiece. The support structure includes a pair of parallel sliding members, wherein the sliding members are disposed in a direction substantially parallel to the cutting axis. The elongated blade is spaced apart from the sliding members and is movable along the sliding members. The cutting edge includes a proximal end and a distal end, wherein an angle between an imaginary line connecting the distal end of the cutting edge to the proximal end thereof and its projection onto the turntable is an acute angle.

Abstract: A cutting assembly for cutting with at least two saw blades simultaneously, includes a motion conversion means comprises: a first part and a plurality of second parts, for example a first bevel gear (30) and a plurality of second bevel gears (32). The first part is arranged for rotation about a central axis thereof and coupled to a drive means (12) for causing the rotation. The first and second parts are arranged such that the rotation of the first part in a direction of rotation causes rotation in a corresponding direction of rotation of each second part about a respective axis extending away from the central axis of the first part. The cutting assembly also includes, for each second part, a coupling means for coupling the second part to a respective cutting blade (100a-f) and including a further motion conversion means, such that the rotation of the second part causes cutting motion of the cutting blade.

Abstract: A hole saw includes a base member configured to secure the hole saw to a drive device and a blade member extending orthogonally from each side of the base member. Each blade member is configured having respective distal ends that flex transversely to a longitudinal cutting direction of the blade member. Responsive to rotational movement of the hole saw via the drive device against a structure, a medial location of each blade member creates an initial respective linear cutting path into the structure, and further movement of the respective blade members into the structure cause the distal ends of the respective blade members to flex transversely to the cutting direction and follow the initial linear cutting path despite the rotational movement of the hole saw relative to the structure to produce a linear cut through the structure.

Abstract: A reciprocating cutting tool is provided, wherein the tool has a reciprocating saw mode and a jig saw mode. The tool includes a reciprocating mechanism; an actuating mechanism and a cutter-lifting mechanism. The reciprocating mechanism includes a reciprocating rod and the cutter-lifting mechanism includes an actuating member and a pushing member. The actuating member includes a first engaging portion and a second engaging portion when the reciprocating rod is driven to perform a reciprocating motion , the reciprocating rod drives the pushing member to deflect close to the first engaging portion or second engaging portion; when the first engaging portion or the second engaging portion is driven to move close to the pushing member, the first engaging portion or second engaging portion pushes the pushing member towards the side which the first engaging portion or the second engaging portion deflects to force the reciprocating rod to implement a cutter-lifting motion.
